In ancient Greece, the word "aigis" (the ancestor of "aegis") literally meant "goatskin." However, it usually referred to a protective cloak, probably made of goat hide, or perhaps to a shield brandished by the god Zeus. Sometimes he entrusted the aegis to other deities, especially his daughter Athena. According to the poet Homer, the center of the aegis bore an image of the Gorgon Medusa's head, and its border was decorated with golden fringe. Many later English writers made reference to the aegis in their works, and by the 18th century, "aegis" was being used figuratively for other kinds of absolute protection.
